Formal concept analysis for identifying mobile subscribers: a case study in a governmental transition project

Traditionally, governmental organizations have provided many supporting services internally. For example, incoming call switching and phone exchange services were often organized as organization-specific team of few people handling the requests. Outsourcing of similar services is a trend in many organizations. In order to minimize service disruption in an outsourcing project, a major problem is to discover the knowledge of current operations. In this paper we describe how we used formal concept analysis to extract classes of mobile subscriptions in the context of a transition project where we changed the provider of our mobile services and outsourced the incoming call switching services from in-house service to a new operator.
